The general idea is to keep the 'old', C-style MEM_callocN signature, and slowly replace most of its usages with the new, C++-style type-safer template version. * `MEM_cnew<T>` allocation version is renamed to `MEM_callocN<T>`. * `MEM_cnew_array<T>` allocation version is renamed to `MEM_calloc_arrayN<T>`. * `MEM_cnew<T>` duplicate version is renamed to `MEM_dupallocN<T>`. Similar templates type-safe version of `MEM_mallocN` will be added soon as well. Following discussions in !134452. NOTE: For now static type checking in `MEM_callocN` and related are slightly different for Windows MSVC. This compiler seems to consider structs using the `DNA_DEFINE_CXX_METHODS` macro as non-trivial (likely because their default copy constructors are deleted). So using checks on trivially constructible/destructible instead on this compiler/system. Pull Request: https://projects.blender.org/blender/blender/pulls/134771
